If rankings weren't a thing, teams would enroll in lots of things. You pay thousands of dollars to be part of travel lacrosse, adding $100 a girl for "Queen of Long Island" sure would beat a scrimmage on a dirt field in Sayville. But unfortunately thoughts like "Is queen of Long Island worth it" exemplify that teams are selective about the things they enroll in. Call this what you want such as "we need to match our level of competition" but the truth is that your kid's team is only enrolling in what's good for the brand- and if you're a top tier team, this means registering for tournaments that will keep you there.
